Hair device has been widely used for the industries such as metallurgy, food, papermaking, air-conditioning, chemical industry and sea water desalination.
Plate-type down-film evaporator is that a kind of novel high-efficiency and energy-saving evaporation equipment and traditional tubular evaparator compare with biography
The thermal efficiency is high, occupied area is small, light weight, easy to make, flexible operation, low energy consumption, less scaling, not easy to foaming, scabs easily
Many advantages, such as voluntarily falling off.Plate-type down-film evaporator is mainly made of heater, distributor, demister and shell etc.,
Wherein heater is the core element of the evaporator.Heater be by a series of sheet metal closed assemblies with dimple shape pit and
At plate periphery Laser Welding straight weld usually carries out laser lap welding in plate face, in particular manufacturing craft to form closed plate spacing
Plate bulging is set to be shaped to dimple shape pit heat transfer plate pressurising plate.Steam carries out condensation biography in the intracavitary flowing of plate when work
Heat, condensed water are flowed out from heating plate lower part header tank.Solution is evaporated in heating plates outer surface by self gravity, along heat exchange
Wall surface forms liquid film, and liquid film-like is made to flow uniformly through generating surface, fast boiling, evaporation, so as to shorten the stop of heating
Time enhances evaporation effect.
Currently, plate-type down-film evaporator is generally used for the rows work such as metallurgy, food, papermaking, air-conditioning, chemical industry and sea water desalination
In industry, thus for heater plate it is generally relatively high, it is relatively long to heat shell side of the steam between two plates, with plate on the outside of object
Material carry out after heat exchange the condensed water that is formed in process from top to bottom can with steam generation heat exchange and take away a part of heat,
To reduce heat transfer efficiency, evaporation efficiency is influenced.Present invention research has carried out structure transformation and upgrade on the basis of original plate,
Its chamber is divided into multiple chambers using herringbone partition, is allowed to shorten the condensed water formed after heating steam progress heat exchange
Shell side prevents condensed water from carrying out heat exchange with heating steam again and takes away heat, to improve heat transfer efficiency.
By the retrieval to patent document, patent document identical with present patent application is not found.
Summary of the invention
